Abstract

Recent wind events in Australia and overseas have caused catastrophic results in those affected areas, with deaths being reported as well as widespread destruction. Research and information gathered from these events have been incorporated into the latest edition of AS/NZS 1170.2-2011 to now represent a more realistic determination of wind actions. The Standard applies to structures ranging from 'the less sensitive to wind action to those for which dynamic response must be taken into consideration'. This handbook was prepared by the AWES to provide background information into wind and its actions, but also into the derivation of the Standard and its contents. It covers items such as: • Nature of wind loading • Wind speeds and multipliers • Shape factors for structures • Dynamic response In particular, it equips users with a better understanding of wind and the Standard to provide them with improved interpretation and judgment in determining wind actions on structures. Equally important, it enables the user to extend the Standard limitations while still complying with regulations, albeit other information may be necessary.
